Exploration potential
• GTK has undertaken statistical estimation of undiscovered, and potentially recoverable metal resources in Finland since 2008
• Au, PGM, Ni, Cu, Zn, Cr for 10 different deposit types
• V, Fe, P, REE, Li, Co under assessement
• USGS three-part quantitative assessment method: 1. evaluation and selection of descriptive and grade-tonnage
models of the deposit types2. delineation of permissive tracts 3. estimation of the number of undiscovered deposits within
each tract• the estimated number of deposits is combined with the
grade and tonnage distributions from the deposit models to assess the total undiscovered metal endowment
The results of the assessment should not be confused with formal industrial standard resource or reserve estimates
Undiscovered resources
• No direct correlation between the size of the belt and totalgold endowment
• There appears to be a log normal size distribution of theorogenic gold districts with prolonged exploration history
• Central Lapland Greenstone Belt (CLGB) data is very skewedcompared to the other belts due to Suurikuusikko Kittilä mine
